Anonymous Letters pv Venus Emerald Frost

An anonymous letter is always a nice way to make a new friend. On the first week of her third year, Cassie walks to the owlery, and gives the letter to a school owl. The letter goes like this:

Hello!
Well, I still don't know who you are by now. I am sending this anonymous letter, so I am not going to reveal my identity as well. I just want to say, I am a third year. Nice to meet you~

Let's do some random chats if you are still interested by now. My favourite subject is Astronomy. What about you?

I am looking forward to your reply! Hope you would like to be anonymous friends with me!

Love, C.
